Exaggerated postural sway improves orthostatic cardiovascular and cerebrovascular control.

Healthy individuals with poor cardiovascular control, but who do not experience syncope (fainting), adopt an innate strategy of increased leg movement in the form of postural sway that is thought to counter orthostatic (gravitational) stress on the cardiovascular system. However, the direct effect of sway on cardiovascular hemodynamics and cerebral perfusion is unknown. If sway produces meaningful cardiovascular responses, it could be exploited clinically to prevent an imminent faint. Twenty healthy adults were instrumented with cardiovascular (finger plethysmography, echocardiography, electrocardiogram) and cerebrovascular (transcranial Doppler) monitoring. Following supine rest, participants performed a baseline stand (BL) on a force platform, followed by three trials of exaggerated sway (anterior-posterior, AP; mediolateral, ML; square, SQ) in a randomized order. All exaggerated postural sway conditions improved systolic arterial pressure (SAP, p = 0.001) responses, while blunting orthostatic reductions in stroke volume (SV, p < 0.01) and cerebral blood flow (CBFv, p < 0.05) compared to BL. Markers of sympathetic activation (power of low-frequency oscillations in SAP, p < 0.001) and maximum transvalvular flow velocity (p < 0.001) were reduced during exaggerated sway conditions. Responses were dose-dependent, with improvements in SAP (p < 0.001), SV (p < 0.001) and CBFv (p = 0.009) all positively correlated with total sway path length. Coherence between postural movements and SAP (p < 0.001), SV (p < 0.001) and CBFv (p = 0.003) also improved during exaggerated sway. Exaggerated sway improves cardiovascular and cerebrovascular control and may supplement cardiovascular reflex responses to orthostatic stress. This movement provides a simple means to boost orthostatic cardiovascular control for individuals with syncope, or those with occupations that require prolonged motionless standing.

RECUPERAÇÃO DE JOGADORES DE BASQUETE APÓS TREINAMENTO DE TÉCNICA OFENSIVA

ABSTRACT Introduction: The shot accuracy and standardization in basketball games are closely related to the quality of the team’s scoring. The percentage of throws is fundamental to know if the basketing movement can be correctly detected and judged. In traditional basketball, players’ skills are composed of specific movements. With the gradual development of these technical movements, coaches should pay more attention to each athlete so that their technical problems can be identified and worked on early. Objective: This article discusses how basketball players move, catch the ball on the court, and execute the shot to the basket. Methods: We randomly and voluntarily selected 90 basketball players by sampling. The independent variables, biomarkers, and kinetic patterns were properly cataloged and processed. The main test items included body, lower limb, and groin circumference. Finally, mathematical statistics were used to analyze the correlation of each index. The relationship between basketball players’ movement posture and basic offensive techniques was analyzed. Results: In basketball, basic attack techniques in multifactorial training remarkably influences their score. The role of score recovery in basketball is significant. Conclusion: The quality of basketing action is directly related to the technical level of offensive basketball. A variety of ball training can improve the skill level of the basketball player. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Effectiveness of Dynamic Neuromuscular Stabilisation and Neurodevelopmental Therapy on Gross Motor Function and Trunk Control in Children with Spastic Diplegic Cerebral Palsy: A Protocol for a RCT

Introduction: The Dynamic Neuromuscular Stabilisation (DNS) technique uses feed forward feedback to involuntarily activate the diaphragm and deep abdominal muscles prior to purposeful movement in humans. It is an efficient approach for facilitating deep core muscle activation of the underactive muscle chain consisting of the Internal Oblique (IO), transverse abdominals and diaphragm, thereby enhancing age appropriate jumping, walking and standing, in participants with Spastic Diplegic Cerebral Palsy (SDCP), whereas the primary goal of Neurodevelopmental Therapy (NDT) is to facilitate more normal movement patterns for performing performance skills and rectifying abnormal postural tone. Need of the study: Even though studies have been done in the past, utilising DNS and NDT in children with diplegic CP, for improving core stability, balance, posture and diaphragmatic movement; however, Gross Motor Function (GMF) and trunk control are the aspects that have not been aimed with DNS. There is scarcity in the literature related to impact of DNS on GMF and trunk control in children with diplegic CP. As DNS has specific role on core strength it can be a valuable in the management of trunk control. Because no study comparing the impact of DNS and NDT on trunk control and functions of gross motor in diplegic children has been found; there is a strong need to perform a study to evaluate the same. Aim: To compare the impact of DNS to NDT on gross motor performance and trunk control in children with SDCP. Materials and Methods: It will be a Randomised Clinical Trial (RCT) with the assessor blinded, conducted in the Outpatient Department of Physiotherapy, AVBRH Sawangi, Meghe, Wardha, Maharashtra, India, from July 2022 to April 2023. Following the baseline assessments, children with SDCP (n=36) will be enlisted and randomly assigned into two groups, groups A and group B. Group A will be treated using conventional therapy along with NDT; group B will be given conventional therapy as well as DNS. Treatment will be given for four weeks, five days a week. On the first and the last day of the intervention, primary outcome measures Gross Motor Function Measure-88 (GMFM-88), Trunk Impairment Scale (TIS) and secondary outcome measure Modified Ashworth Scale (MAS) will be employed (on the first day and after the completion of four weeks). Mini-mental Scale Examination (MMSE) will be used as inclusion criteria for the children. Statistical analysis will be carried out using Statistical Package for the Social Sciences (SPSS) software version 27.0. Conclusion: The present study is expected to prove that DNS approach to be successful in enhancing the control of the trunk and gross motor abilities in children with SDCP.

A Multi-Hop QoS-Aware and Predicting Link Quality Estimation (PLQE) Routing Protocol for Reliable WBSN

Technological advancements and miniaturization of sensor have made it possible to use tiny size sensors nodes to monitor patients’ physiological data in real-time at very low cost. The network of such small size sensor nodes is often called wireless body sensor networks (WBSNs). The patient’s data is highly sensitive which required to reach reliably and timely at the destination node. However, short range wireless nodes and postural body movements cause frequent topological changes and recurrent network partitioning. The network partitioning leads to delayed and significant loss of critical patient’s data such as Electrocardiogram (ECG), Electroencephalogram (EEG) and Electromyogram (EMG). Therefore, QoS requirement of WBSNs in terms of reliability, end-to-end delay and throughput are highly compromise. We in this paper propose a Predicting routing protocol PLQE to address reliable data transmission and network partitioning due to node mobility. The PLQE dynamically determines the efficient links by using beta probability density function, link quality and link delay estimation (LDE). The PLQE is composed of link reliability factor (LRF) and expected probability Indicator (EPI) to obtain most often updated status of the links to figure out stable and reliable end to end route to the destination node. The simulation results confirm the higher performance of the proposed scheme against state of the art routing protocols in terms of packet delivery ratio, end to end delay, throughput and normalized routing load.

An improved deep neural network method for an athlete's human motion posture recognition

Aiming at improving the accuracy of motion gesture recognition and reducing the time-consuming recognition, this paper proposes an athlete's body motion gesture recognition method based on improved deep neural network. According to the movement characteristics and basic structural characteristics of the human body, the movement posture recognition standard is designed and set in the model. Collect athletes' human motion images, and perform motion image extraction, residual compensation, filtering, normalisation, and morphological processing. On this basis, the features of human motion images are extracted and fused. The recognition classifier is constructed based on the improved deep neural network, the fused feature vector is input into the classifier, and the recognition result is output. The results of the comparative experiment show that the proposed method has a high recognition rate and short overhead time only at 1.2 s.

Dance pose capture and recognition based on heterogeneous sensors

In order to capture the movement posture of dancer in real time and effectively, a dancer motion and posture capture system based on heterogeneous sensors is proposed. Starting from the data processing of heterogeneous sensors in a single node, the single attitude measurement node of the system can be used to collect the initial posture data in the process of dancer motion in real time, achieve accurate capture of dancer movements, and filter and fuse the original motion data. In order to verify the performance and accuracy of the designed dancer movements capture system, relevant experiments are designed to verify it. The experimental results show that the algorithm designed in this experiment basically solves the interference problem of magnetic field and acceleration on attitude solution, and the attitude solution accuracy can basically meet the requirements. The fitting degree of the comparison between the extracted angle of the video sequence and the output angle of the sensor can basically meet the requirements, and the angle deviation is kept within 1 degree. The system can capture the dancer movements of the whole body and the hand, and the experimental results can meet the requirements basically, which has certain reference value.

IMMEDIATE EFFECTS OF POST FACILITATION STRETCH TECHNIQUE ON STRAIGHT LEG RAISE WITH/WITHOUT THORACO-LUMBER DIRECT MYOFACIAL RELEASE IN NON-SYMPTOMATIC ADULTS

Background: Hamstring tightness is a condition which if it is remaining untreated it could be related later on to the posture imbalance and movement restriction. There are many techniques to increase the elasticity of hamstrings. Post facilitation stretching (PFS) along with thoraco-lumbar direct myofascial release (MFR) technique is emerging as a novel therapy for improving hamstring muscle length. Objective: To determine the immediate effects of post facilitation stretching technique on SLR with/without thoraco-lumber direct myofascial release on straight leg raise among non-symptomatic adults. Methods: A randomized control trial (RCT) was conducted at FIMS College of rehabilitation Abbottabad Pakistan after approval from HOD. A total of n=24 non symptomatic adults were recruited through non-probability convenient sampling technique. The inclusion criteria were non symptomatic adults with tight hamstrings, age group 18 to 40 years, normal healthy adults, both gender groups, SLR (passive) of 80° degree or less, finger floor distance of 5 cm or more. The participants were than randomly divided into two control group (n=12) and experimental group (n=12). The post facilitation stretch technique was applied in both groups, but experimental group additionally received thoraco-lumber direct myofascial release technique as well. To assess the total mobility of the lumbo-pelvic region and hamstring elasticity fingertip to floor distance was measured and straight leg raise test with the help of goniometer. The data was collected at the baseline and immediately after session. Results: The mean age of the study participant was 23.41±2.31 years. The pre-post analysis showed that right and left straight leg raise (SLR) as well as fingertip floor distance were significantly (p&lt;0.001) improved immediately after the intervention with large effect size. When compared both groups immediately after the intervention, experimental group which received myofascial release in addition post facilitation stretch showed more significant improvement with large effect size in right &amp; left SLR and fingertip floor distance (p&lt;0.001) as compared to control group where only post facilitation stretch technique was applied. Conclusions: The present study concluded that post facilitation stretch along with the thoracolumbar direct myofascial release technique significantly improve hamstrings flexibility. The efficacy of thoracolumbar direct myofascial release has contributed in increasing SLR and Finger Floor Distance tests parameters. Keywords: hamstring, muscle length, myofascial release, muscle energy technique, post facilitation stretch, stretching exercises.

THE IMPACT OF 12 WEEKS OF ADAPTED DANCE ON BALANCE, GAIT, AND LOWER EXTREMITY FUNCTION AMONG PERSONS WITH DEMENTIA

Abstract Person’s living with dementia commonly experience difficulty with mobility. Difficulties with these activities can lead to an increased fall risk, resulting in an increased loss of independence. Dance engages various parts of the brain including the cerebellum that is primarily involved in coordinating balance, posture, body positioning, and voluntary movement. An aim of this study was to assess whether 12 weeks of adapted dance improves balance, usual walking speed, and lower extremity function among persons living with dementia. An experimental design was used to randomly assign persons with dementia to either a 12-week adapted dance or social stimulation group. The convenience sample consisted of 12 participants, ages ranging from 62–97 years. The adapted dance is low impact where one foot is always in contact with the floor and is appropriate for older adults with cognitive and physical limitations. At baseline and at 12 weeks, measures of balance, gait, and lower extremity function were assessed. From baseline to posttest, the dance group had greater increased times for maintaining tandem balance (+47.5%) and faster times for usual gait speeds (+15.1%); compared with the social stimulation group tandem balance time (+0.98%) and usual gait speed times (+10.5%). A limitation of this study is the small sample size.

Postural instability-induced compensative movements in virtual reality

During virtual reality usage, two egocentric mental representations are constructed simultaneously. The first representation is rooted in the physical reality in which VR is set up, and the second originates from the mental construction of a computer-generated virtual environment. In both cases, participants configure their posture based on multimodal stimuli while responding to environmental cues. In most cases, the postural cues provided by the digital and real environment may be conflicting. In this study, 50 right-handed volunteers were enrolled. In a pre-test session, attentional focus-related personality bias (perspective-taking) was assessed, and afterward, postural movements and presence experiences were measured while the participants performed a spatial orientation task in VR. Participants were placed in an upright position with their right hands positioned in front of a physically real point on the laboratory wall. Afterward, participants were exposed to a VR environment in which they performed a room-tilting task. Participants with higher hand-related presence scores showed decreased compensatory hand drift in the VR environment. The rate of contralateral hand drift showed a reversed association with the intensity of the perspective-taking trait. VR-induced postural instability can be attenuated by the compensative hand drift that alleviates the conflicts between the two rival inner VR and outer VR environments that compete for attention and provide different reference cues.

Ergonomic Risk Factors for Musculoskeletal Disorders among Ethnic Lychee-Longan Harvesting Workers in Northern Thailand.

Musculoskeletal disorders (MSDs) are one of the leading causes of occupational injuries and disabilities. The purpose of this study was to assess the prevalence of MSDs and occupational factors affecting MSDs among ethnic lychee-longan harvesting workers in northern Thailand. A cross-sectional study was conducted in the areas of three upper northern provinces of Thailand. The study areas are located in the highlands and rural plains, where many ethnic minority groups live, including Indigenous, Mien, Karen, and Lua. The majority of them work in a farm of perennial fruit trees, mainly lychee and longan. During the harvest season, 404 participants were recruited for the study using the convenience sampling technique. Data were collected using questionnaires that included general information, an ergonomic risk assessment, and a standardized Nordic questionnaire for assessing MSDs in 10 body parts. The average age of lychee-longan harvesting workers was 48.8 years. Almost all (99.5%) reported MSDs in one or more body regions in the previous seven days of work. The prevalence of MSDs was highest in the hands (82.9%), followed by the shoulders (82.2%) and the neck (79.7%). The total ergonomic risk scores, which included awkward posture, heavy carrying and lifting, repetitive activity, land slope, and equipment, were found to be significantly associated with MSDs in part of the neck (AOR = 1.17, 95%CI = 1.11-1.23), shoulder (AOR = 1.15, 95%CI = 1.10-1.21), elbow (AOR = 1.18, 95%CI = 1.12-1.24), hand (AOR = 1.12, 95%CI = 1.07-1.18), finger (AOR = 1.33, 95%CI = 1.24-1.44), upper back (AOR = 1.14, 95%CI = 1.09-1.20), lower back (AOR = 1.16, 95%CI = 1.11-1.22), hip (AOR = 1.11, 95%CI = 1.06-1.15), knee (AOR = 1.18, 95%CI = 1.12-1.24), and feet (AOR = 1.21, 95%CI = 1.15-1.28) when adjusting for ethnicity, sex, age, BMI, and work experience. Many parts of ethnic workers' bodies have been affected by occupational injuries, with a high risk of upper extremity injury. As a result, using an ergonomic approach to improving the working environment and appropriate posture movement is very beneficial in preventing MSDs among ethnic harvesting workers.

Efficacy of bed exercise in elderly patients after total hip arthroplasty: A retrospective study of 539 patients.

The purpose of this study was to observe the necessity of bed exercise therapy in the rehabilitation of elderly patients after hip replacement and to analyze whether bed exercise therapy has an impact on patients' psychological scores, hip function and postoperative complications. From January 2018 to January 2021, a total of 539 patients with end-stage femoral head necrosis or hip osteoarthritis were retrospectively analyzed. According to the method of postoperative rehabilitation exercise, patients were divided into 2 groups: Group A (routine gait) and Group B (bed exercise). There was no significant difference in general information between the 2 groups. There was no significant difference in baseline pain scores between patients in Group A and Group B (25.2 ± 9.6 vs 24.8 ± 10.4, P = .429). However, at 5 weeks post-operatively, the pain scores of patients in Group A were significantly higher than those in Group B (38.6 ± 7.7 vs 34.1 ± 8.1, P = .016). At 17 weeks post-operatively, the difference between Group A and Group B remained (40.9 ± 6.9 vs 37.5 ± 7.5, P = .041). Similar to the pain score, the hip function score compared between the 2 groups was significantly different at 5 weeks (39.7 ± 8.4 in Group A, 45.9 ± 9.2 in Group B, P < .001) and 17 weeks post-operatively (41.5 ± 7.6 in Group A, 47.2 ± 8.8 in Group B, P < .001). At 17 weeks post-operatively, between the 2 groups, only the range of motion (ROM) of abduction showed no significant difference. Patients in Group B exhibited a better ROM in any other movement posture. The results showed that compared with Group A, bed exercise rehabilitation training could reduce the incidence of deep venous thrombosis. This study demonstrates that bed exercise can improve the hip function and quality of life of elderly patients with total hip arthroplasty (THA) at an early postoperative stage. It can reduce the incidence of deep venous thrombosis of the lower limbs after surgery. For these patients, systematic bed exercise rehabilitation training is recommended in the early postoperative period.

Muva physical activity intervention to improve social functioning in people with a severe mental illness: study protocol of a pragmatic stepped wedge cluster randomized trial

BackgroundPeople with severe mental illness (SMI) often suffer from long-lasting symptoms that negatively influence their social functioning, their ability to live a meaningful life, and participation in society. Interventions aimed at increasing physical activity can improve social functioning, but people with SMI experience multiple barriers to becoming physically active. Besides, the implementation of physical activity interventions in day-to-day practice is difficult. In this study, we aim to evaluate the effectiveness and implementation of a physical activity intervention to improve social functioning, mental and physical health.MethodsIn this pragmatic stepped wedge cluster randomized controlled trial we aim to include 100 people with SMI and their mental health workers from a supported housing organization. The intervention focuses on increasing physical activity by implementing group sports activities, active guidance meetings, and a serious game to set physical activity goals. We aim to decrease barriers to physical activity through active involvement of the mental health workers, lifestyle courses, and a medication review. Participating locations will be divided into four clusters and randomization will decide the start of the intervention. The primary outcome is social functioning. Secondary outcomes are quality of life, symptom severity, physical activity, cardiometabolic risk factors, cardiorespiratory fitness, and movement disturbances with specific attention to postural adjustment and movement sequencing in gait. In addition, we will assess the implementation by conducting semi-structured interviews with location managers and mental health workers and analyze them by direct content analysis.DiscussionThis trial is innovative since it aims to improve social functioning in people with SMI through a physical activity intervention which aims to lower barriers to becoming physically active in a real-life setting. The strength of this trial is that we will also evaluate the implementation of the intervention. Limitations of this study are the risk of poor implementation of the intervention, and bias due to the inclusion of a medication review in the intervention that might impact outcomes.Trial registrationThis trial was registered prospectively in The Netherlands Trial Register (NTR) as NTR NL9163 on December 20, 2020. As the The Netherlands Trial Register is no longer available, the trial can now be found in the International Clinical Trial Registry Platform via: https://trialsearch.who.int/Trial2.aspx?TrialID=NL9163.

Movement smoothness during dynamic postural control to a static target differs between autistic and neurotypical children

BackgroundAutistic children and adults have known differences in motor performance, including postural instability and atypical gross motor control. Few studies have specifically tested dynamic postural control. This is the first study to quantify movement smoothness and its relationship to task performance during lateral dynamic postural control tasks in autism. Research questionWe sought to test the hypothesis that autistic children would have less smooth movements to lateral static targets compared to neurotypical children, and that this difference would relate to specific movement strategies. MethodsWe used camera-based motion-capture to measure spatiotemporal characteristics of lateral movement of a marker placed on the C7 vertebrae, and of markers comprising trunk and pelvis segments during a dynamic postural movements to near and far targets administered in an immersive virtual environment. We tested a sample of 15 autistic children and 11 age-matched neurotypical children. We quantified movement smoothness using log dimensionless jerk. ResultsAutistic children exhibited more medial-lateral pelvic position range of motion compared to neurotypical children, and used a stepping strategy more often compared to neurotypical children. Autistic children also had higher log dimensionless jerk than neurotypical children for motion of the C7 marker. All participants had higher log dimensionless jerk for far targets than for near targets. Autistic children had longer trial durations than neurotypical children, and younger children had longer trial durations than older children across diagnostic groups. SignificanceThe stepping strategy observed more often in the autistic group likely contributed to log dimensionless jerk and reduced movement smoothness. This strategy is indicative of either an attempt to prevent an impending loss of balance, or an attempt to compensate for and recover from a loss of balance once it is detected.

Effects of different virtual reality technology driven dual-tasking paradigms on posture and saccadic eye movements in healthy older adults

Postural sway and eye movements are potential biomarkers for dementia screening. Assessing the two movements comprehensively could improve the understanding of complicated syndrome for more accurate screening. The purpose of this research is to evaluate the effects of comprehensive assessment in healthy older adults (OA), using a novel concurrent comprehensive assessment system consisting of stabilometer and virtual reality headset. 20 healthy OA (70.4 ± 4.9 years) were recruited. Using a cross-sectional study design, this study investigated the effects of various dual-tasking paradigms with integrated tasks of visuospatial memory (VM), spatial orientation (SO), and visual challenge on posture and saccades. Dual-task paradigms with VM and SO affected the saccadic eye movements significantly. Two highly intensive tests of anti-saccade with VM task and pro-saccade with SO task also influenced postural sway significantly. Strong associations were seen between postural sway and eye movements for the conditions where the two movements theoretically shared common neural pathways in the brain, and vice versa. This study suggests that assessing posture and saccades with the integrated tasks comprehensively and simultaneously could be useful to explain different functions of the brain. The results warrant a cross-sectional study in OA with and without dementia to explore differences between these groups.

SleepCon: Sleeping Posture Recognition Model using Convolutional Neural Network

Recognition of sleep patterns and posture has sparked interest in various clinical applications. Sleep postures can be monitored autonomously and constantly to provide useful information for decreasing health risks. Existing systems mostly use images to train the model to learn based on many sensors. For example, a camera, pressure sensor, and electrocardiogram. In this study, a model (named as SleepCon) was designed using deep learning, which will have the capability to train with any threshold image obtained from any sensor. This paper presented a system where data was obtained from a camera installed on the top of a mattress. The camera located the movement of the body posture on the mattress while the subject was lying down on the mattress. In doing so, CNN and other pre-processed steps took place to collect data and then analyze the data to recognize different sleep postures. This model was stored for use in real-time applications. The system can recognize the three major postures, i.e., left, right, and supine. A real-time application is also developed and operates the stored SleepCon model through an accompanying desktop application for detecting the posture live. The accuracy of classification was greater than 90%, while the actual application accuracy was 100% after carrying out the experiment on the SleepCon model.

Treatment available for neurogenic TOS included conservative treatment with physiotherapy for posture and shoulder movement correction.&#x0D; Conclusion: TOS is a condition that could cause a variety of symptoms. Appropriate investigations and multiple diagnostic tests are needed for establishing the diagnosis. Patient’s history, clinical presentation, and examination could help eliminates the differentials, with imaging and electrophysiological testing helps identify the etiology.&#x0D; Keywords: Thoracic outlet syndrome, patent ductus arteriosus, scoliosis

Cloud Computing Image Processing Application in Athlete Training High-Resolution Image Detection

The rapid development of Internet of things mobile application technology and artificial intelligence technology has given birth to a lot of services that can meet the needs of modern life, such as augmented reality technology, face recognition services, and language recognition and translation, which are often applied to various fields, and some other aspects of information communication and processing services. It has been used on various mobile phone, computer, or tablet user clients. Terminal equipment is subject to the ultralow latency and low energy consumption requirements of the above-mentioned applications. Therefore, the gap between resource-demanding application services and resource-limited mobile devices will bring great problems to the current and future development of IoT mobile applications. Based on the local image features of depth images, this paper designs an image detection method for athletes' motion posture. First, according to the characteristics of the local image, the depth image of the athlete obtained through Kinect is converted into bone point data. Next, a 3-stage exploration algorithm is used to perform block matching calculations on the athlete's bone point image to predict the athlete's movement posture. At the same time, using the characteristics of the Euclidean distance of the bone point image, the movement behavior is recognized. According to the experimental results, for some external environmental factors, such as sun illumination and other factors, the image detection method designed in this paper can effectively avoid their interference and influence and show the movement posture of athletes, showing excellent accuracy and robustness in predicting the movement posture of athletes and action recognition. This method can simplify a series of calibration tasks in the initial stage of 3D video surveillance and infer the posture of the observation target and recognize it in real time. The one that has good application values has specific reference values for the same job.

Plantar Pressure Distribution Measurement System Based on PVDF Piezoelectric Senors

During people’s normal movement, the sole of foot is the only part of human body that contacts with the ground. The pressure information of sole directly reflects the physiological health and movement posture of human. A plantar pressure measurement system was designed with an insole type for measuring plantar pressure during normal movement. The insole embedded five PVDF piezoelectric film sensors, and then places the insole in the measured sports shoes. In order to obtain better pressure response effect, two small raised blocks were pasted under each piezoelectric film sensor to increase the sensitivity of the sensor. The plantar pressure data was sent to PC by wireless serial port. An intuitive and easy-to-use GUI interface was designed by the MATLAB software. The interface can display the pressure distribution at each point of the sole of both feet.
